Decimal precision (only for numeric attributes)

The precision of a value is defined the number of digits that is used to express that value. This property indicates the number of decimal places (the number of digits following the decimal point).

Behavior Properties

Show tooltip

This property determines whether the tooltip form is shown as the mouse is hovered over this column. The tooltip form can be configured on the Data Grid.

Default value: False

Aggregate function

The values in a column can be aggregated in several ways. The aggregate function determines the way in which the values are aggregated. The aggregate will be shown at the bottom of the column that precedes by the aggregate caption (see below).

Value

Description

None

Do not aggregate the values in the column.

Average

Show the average of the values.

Minimum

Show the smallest value.

Maximum

Show the largest value.

Sum

Show the sum of the values.

Count

Show the count of the values.

Note that all objects will be taken into account, and not just the ones on the current page.

Aggregate caption

The aggregate caption is the text that appears in front of the computed value. This is a translatable text. See Translatable Texts.

‘Total’ could be an aggregate caption for a column that shows the sum of the values.

Editable

The editable property indicates whether the values of the column will be editable in-line, i.e. without opening a form with a data view. In-line editing allows the data grid to behave like you would expect from a spreadsheet application.

Data Source Properties

Attribute (path)

The attribute (path) property specifies the attribute’s value that will be displayed in this column. It can be an attribute of the grid entity, or it can be an attribute of an associated entity, in which case we speak of an attribute path. The path can follow multiple associations of type reference, and at the end (optionally) one of type reference set. If you show a reference set in a column the values will be separated by a comma.
